Physical review letters

Lunghi T, Kaniewski J, Bussières F, Houlmann R, Tomamichel M, Kent A, Gisin N, Wehner S, Zbinden H.
PMID: 24237497
Phys Rev Lett. 2013 Nov 01;111(18):180504. doi: 10.1103/PhysRevLett.111.180504. Epub 2013 Nov 01.

Bit commitment is a fundamental cryptographic primitive in which Bob wishes to commit a secret bit to Alice. Perfectly secure bit commitment between two mistrustful parties is impossible through asynchronous exchange of quantum information. Perfect security is however possible...

Determination of dissolved oxygen in heterogenous systems particularly in emulsions and oily liquids.

Pharmaceutical research

Foiβner KH, Leonhardt A, Wegner G, Heinz Bauer K.
PMID: 24272514
Pharm Res. 1985 Jan;2(1):44-6. doi: 10.1023/A:1016370123621.

The content of dissolved oxygen was determined by four independent methods in a series of non-aqueous or heterogenous systems. The Lex-O2-Content Analyzer represents a fast and simple apparatus that employs a coulometric oxygen assay with Hersch cell detection. A...

First observation of the fourth neutral polarization point in the atmosphere.

Journal of the Optical Society of America. A, Optics, image science, and vision

Horváth G, Bernáth B, Suhai B, Barta A, Wehner R.

In the clear sky there are three commonly known loci, the Arago, Babinet, and Brewster neutral points, where the skylight is unpolarized. These peculiar celestial points, bearing the names of their discoverers, have been the subject of many ground-based...

Crystalline self-assembly into monolayers of folded oligomers at the air-water interface.

Chemistry (Weinheim an der Bergstrasse, Germany)

Lederer K, Godt A, Howes PB, Kjaer K, Als-Nielsen J, Lahav M, Wegner G, Leiserowitz L, Weissbuch I.
PMID: 10926223
Chemistry. 2000 Jun 16;6(12):2173-83. doi: 10.1002/1521-3765(20000616)6:12<2173::aid-chem2173>3.0.co;2-e.

Insertion of the 1,3-bis(ethynylene)benzene unit as a rigid spacer into a linear alkyl chain, thus separating the two resulting stems by 9 A. induces chain folding at the air-water interface. These folded molecules self-assemble into crystalline monolayers at this...

Complex morphogenesis of surfaces: theory and experiment on coupling of reaction-diffusion patterning to growth.

Faraday discussions

Harrison LG, Wehner S, Holloway DM.
PMID: 11901681
Faraday Discuss. 2001;(120):277-94; discussion 325-51. doi: 10.1039/b103246c.

Reaction-diffusion theory for pattern formation is considered in relation to processes of biological development in which there is continuous growth and shape change as each new pattern forms. This is particularly common in the plant kingdom, for both unicellular...

Prognostic and predictive implications of HER2 status for breast cancer patients.

European journal of oncology nursing : the official journal of European Oncology Nursing Society

Women diagnosed with breast cancer face many emotional and psychological challenges, which are often related to how they perceive their chances of survival. A number of factors are known to be indicators of breast cancer prognosis, including tumour type,...

Up-conversion fluorescence: noncoherent excitation by sunlight.

Physical review letters

Baluschev S, Miteva T, Yakutkin V, Nelles G, Yasuda A, Wegner G.
PMID: 17155253
Phys Rev Lett. 2006 Oct 06;97(14):143903. doi: 10.1103/PhysRevLett.97.143903. Epub 2006 Oct 04.

We demonstrate up-conversion of noncoherent sunlight realized by ultralow excitation intensity. The bimolecular up-conversion process in our systems relies on the presence of a metastable triplet excited state, and thus has dramatically different photophysical characteristics relative to the other...
